Landslide influence on delta stratigraphy, northeastern Gulf of Mexico

Our detailed mapping and analysis of shelf-margin evolution in the northeastern Gulf of Mexico during the last half million years are useful as a process analog for older, poorly imaged, and/or locally sampled subsurface intervals there and in other settings with delta-fed submarine channels.
